The Mercury 7 mission. The audio files are named as per their original historical audio reel number at the NASA historical audio vault. Information listed below is the sum-total of data on these reels.
INFORMATION ON THE AUDIO FILES:
461-AAG: 5/24/1962, Scott Carpenter
462-AAG: 5/24/1962, Excerpts-liftoff,sightings, Indian Ocean ships, night check list, re-entry
Spacecraft No. 18 (Aurora 7), Vehicle Number 107-D
Corroborate man-in orbit
May 24, 1962. 7:45:16 EST. The launch countdown proceeded almost perfectly, with only a last-minute hold of 45 minutes occuring at the T-11 minutes mark in anticipation of better camera coverage and to allow aircraft to check the atmospheric refraction index in the vicinity of Cape Canaveral. The launch vehicle used to accelerate Carpenter and the Aurora 7 spacecraft was an Atlas D. The differences between the Atlas 107-D launch vehicle and the Atlas 109-D used for MA-6 involved retention of the insulation bulkhead and reduction of the staging time from 131.3 to 130.1 seconds after liftoff.
The performance of the launch vehicle was exceptionally good with the countdown, launch and insertion conforming very closely to planned conditions. At sustainer engine cuttof (SECO) at T+5min10sec, all spacecraft and launch vehicle systems were go and only one anomaly occured during launch. The abort sensing and implementation system (ASIS) Hydraulic switch No. 2 for the sustainer engine actuated to the abort position at 4:25 minutes after liftoff. Pressure transducer H52P for the sustainer hydraulic accumulator was apparently faulty and showed a gradual decrease in pressure from 2,940 psia to 0 between 190 and 312 seconds after liftoff. Another transducer in the sustainer control circuit indicated that pressure had remained at proper levels so the switch did not actuate until the normal time after SECO.

Spacecraft overshot intended target area by 250 nautical miles. After landing, Carpenter reported a severe list angle on the order of 60 degrees from vertical and postflight photographs of the spacecraft taken after egress indicated approximately a 45 degree list angle. An Air Rescue Service SA-16 amphibian aircraft established visual contact with the spacecraft 39 minutes after landing (1:20pm) and the USS Farragut, located about 90 nautical miles southwest of the calculated landing position was first to reach the capsule.
Carpenter was picked up by HSS-2 helicopters dispatched from the aircraft carrier USS Intrepid (CVS-11) while the destroyer USS Farragut (DLG-6) watched the Aurora 7 capsule until it could be retrieved with special equipment aboard the USS John R. Pierce about 6 hours later. A Considerable amount of sea water was found in the spacecraft which was believed to have entered through the small pressure bulkhead when Carpenter passed through the recovery compartment into the liferaft. The spacecraft was delivered by destroyer to Roosevelt Roads, Puerto Rico with subsequent return to Cape Canaveral by airplane.
Total time weightless 4 hours 39min 32sec. The performance of the Mercury spacecraft and Atlas launch vehicle was excellent in nearly every respect. All primary mission objectives were achieved. The single mission critical malfunction which occured involved a failure in the spacecraft pitch horizon scanner, a component of the automatic control system. This anomaly was adequately compensated for by the pilot in subsequent inflight operations so that the success of the mission was not compromised. A modification of the spacecraft control-system thrust units were effective. Cabin and pressure-suit temperatures were high but not intolerable. Some uncertainties in the data telemetered from the bioinstrumentation prevailed at times during the flight; however, associated information was available which indicated continued well-being of the astronaut. Equipment was included in the spacecraft which provided valuable scientific information; notably that regarding liquid behavior in a weightless state, identification of the airglow layer observed by Astronaut Glenn, and photography of terrestrial features and meteorological phenomena. An experiment which was to provide atmospheric drag and color visibility data in space through deployment of an inflatable sphere was partially successful. The flight further qualified the Mercury spacecraft systems for manned orbital operations and provided evidence for progressing into missions of extended duration and consequently more demanding systems requirements.

Mercury 7 audio
Audio player and mp3 in. Audio goes all the way to 4:55 after chutes are out and capsule below 5000 feet above sea level.
Audio goes past time indicated in player. Sound cuts out a couple times after 3:25. Don't be fooled by that. It comes back in.

Thank you NASA for the hard work of reconstructing this audio from very old tapes and thanks to Archive people here for converting .wav files and to Jeff finishing with mp3 files and audio player on this page.

Need mp3 version
.wav file isnt working for me. Who can convert the .wav to an mp3 file? Thanks.
